There is no specific formula for sizing the cable, it depends upon some factors which must be taken in to account during cable sizing such as,


1. Route length.

2. Environmental temperature.

3. Lay in air or buried.

4. Grouping factor.

5. Safety/ageing factor.

6. Peak starting current of load and duration.


May be there are many other factors which can be added by other experts.
